PULIJEY ATTACHMENT FOR WHEELS.

Specification of Letters Patent.

Application filed lday 20, 1915. Serial No. 29,376.

T 0. all whom it may concern Be it known that I, 'JAoon S. BAUGHMAN, a citizen of the United States, residing at urlington, in the county of Des Moines and State of Iowa, have invented anew and useful Pulley Attachment for Wheels, of

which the following is a specification.

This invention relates to an improvement in attachments for automobile wheels, and the object is to provide a pulley which can be removably connected to a rear or drive wheel of an automobile so that upon the the ground power can betaken from the drive wheel for the purpose of transmitting power to a grinding machine, pump, saw mill, sewing machine, washing machine and the like.

Another object of the invention -is in the manner of mounting the pulley upon the drive wheel which is accomplished by attaching clips or clamps to rotatable spokes of the pulley whereby upon the rotation of the pulley spokes the clamps will be brought into engagement with the 'rim of the drive wheel.

The invention consists of certain novel features of construction and combination of parts which will be hereinafter described in the following claims.

It is to be understood that many slight changes may be made in form and arrangement of the several parts described without departing from the spirit and scope of the invention, and hence I do not'wish to limit myself to the exact disclosure herein set forth.

In the drawings Figure l is a view in elevation of a machine or automobile, showing'the invention applied. Fig. 2 is a vertical sectional View through an automobile Wheel and fully disclosing the invention.

ig. 3 is a View in side elevation of the pulley. Fig. 4 is a top plan view of the clamp and Fig. 5 is a perspective view of the clamp which is applied to the spokes of the drive wheel. p v

A represents an automobile.

l is the front wheel, which is mounted in an anchor lock 2 for holding the wheel against 'mmement. The rear ordrive wheel 3 is supported above the ground by a jack 4. A pulley 5 of any approved form is provided with a plurality of spokes 6. Connected to the inner ends of diametrically opis moved vertically posite spokes is a hub or bearing 7 which is provided with an openin or recess 8.

he outer terminals 0 the severalspokes are provided with screw threads'9, and the spokes are connected to the rim'lO of the.

pulley by means of plates 11 which are provided with openings iniwhich the ends of the spokes are received. The plates 11 are connected to the rim of the pulley by means of boltsand nuts 12 and 13. Suitable clamps are mounted upon the s okesfi'which consist of sections 14 and 15. he two'sections are provided with grooves-l6 So that when the two sections are broughttogether a groove or circularopening isformed in which the spoke 17 of the wheel 3 may be received. The hole is preferably of a size to permit the free sliding movement of the sections or clamp upon the spoke, and the wall of the.

openlng is covered with some material, such as felt or rubber to prevent the injury or removal of the paint and varnish on the spokes. 1

' The section 14 of the clamp is provided with a right angular portion 1.8 which has a head 19 connected-thereto provided with a central screw-threaded bore. The spokes 6 are received in the bore of the head 19 and the screw threads 9 of the spokes engage the screw threads of the head, so that the clamp pulley, and the causing the jaws 20 of the sections 14 and 15 to be brought into engagement with the rim 21 of the wheel 3, a jaw of each section being received on opposite sides of the rim. formed on the section 11p or flange 22. 1s 15 and a bolt 23 passes through the flange or of the spokes 6 of the spokes 17 of the Wheel 3 for Patented Maya, 191 j 11p to): connecting sections 14 andl5 together. A nut 24 is screwed upon the bolt 23 for confining the two sections together.

When it 1s desired to apply a clamp to the rim or folly of a, wheel the spokes 6 are rotated by inserting a tool in the opening or recess 8 of the hub- 7, which causes, upon the rotation of the hub, the spokes to revolve and moves the'clamps "ertically and brings the jaws gginto or the-rim or felly 21.

When the sections 14 and 15 of the clamp have been elevated upon the spokes 6 sulficiently to cause the proper engagement between'the clamp and the rim 21 of the wheel 3, the locking nut 30 on the spokes 6 will be out of engagement with adapted to engage a drive wheel, and means screwed. into engagement with the head19 of the clamp for locking therclamp against movement and thereby maintaining the clamp in engagement with the rims 21 of the wheel 3.

In some instances the opening formed the clamp by the groove 16 may-not be of su ficien't size to permit of a tree sliding incvement an the spokes, and in such in- 1'() stance the holt 23 would be'floosened suffi' ciently' sothat the clamp may be moved and after the clamp has been brought into position the bolt 23 will be tightened for holding the tivo sections rigidly upon the spoke. When it is desircdflto remove the spokes 6 from the pulley the plates 12 are disconnected and the spokes can then be re-.

moved orinserted.

As illustrated in Fig. 1, power can be taken from the pulley 5 by a, belt 26 for transmitting the. power to the pulley 27 and shaft 28 for the purpose of delivering the power to any suitable machine or apparatus from the shaft 28. Power may be taken upon' the spokes of thedri've wheel, and

means for moving the clamps into engagement with the rim of the drive wheel.

2. The combination with a drive Wheel, of p a' pulley consisting of a rim and spokes,

clamps movably mounted on said spokes for causing the olarnps to be. brought into eng gement with the drive wheel for fasten-- ing the pulley thereto.

3. The combniatio'n of a drive-wheel, a

pulley having rotatable spokes, clamps mounted upon the spokes, and means for ro- I tating the spokes for causing the' clamps to 'be brought into engagement with the drive wheel for fastening the pulley to the wheel.

4. The combination 'Wlth a drive wheel, of a pulley having rotatable spokes, clamps having screw threaded engagement with the spokes, and means for rotating the spokes for causing the clamps to engage the'drive wheel and lock the pulley thereto.

5. The combination with a drive wheel consisting of a rim and spokes, of a pulley provided with rotatable spokes, a clamp made of two sections adapted to be placed upon'a spoke of the drive wheel, Iineansfor connecting the two sections together, jaws on the sections adapted to be brought into engagement with the rim of the drive wheel, and means for connectin the sections to the spokes of the pulley whereby upon the rotatlon of said spokes the clamp willbe brought into engagement with the rim of the drive wheel.

6-.- The combination of a rim, rotatable spokes',.-means for connecting the s okes to the-rim, and clamps carried by saidspokes adapted to be moved vertically upon the rotat-ion of said s okes.

7. The combination with a drive wheel consisting of a rim havin spokes, of, a pulley arranged alon side t e drive wheel; and clampin devices carried by the pulley and provide with jaws to engage the rim of the drive wheel.

' ,8. The combination with a drive'wheel consisting of a rim having spokes, of a pulley also having'a rim and spokes, and clamping 'devices mounted upon and connecting the spokes of the pulley and wheel and provided with jaws to'oengage the rim of the drive wheel. I

In testimony that l claim the foregoing,

asimy own, I have hereto afiixed my slgnature in the resence of two witnesses.-
